Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery if working on the electrical components.

2. Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts with a socket set and take off the wheel.

3. Inspect Brake Components

Remove the brake caliper by loosening the caliper bolts with a socket set.
Carefully slide the caliper off the rotor and support it with a wire or bungee cord to avoid stressing the brake line.
Measure the thickness of all brake pads and note any discrepancies.
Inspect brake rotors for uneven wear or damage and replace if necessary.

4. Check Caliper and Suspension

Inspect the caliper for proper movement; ensure the caliper slides are lubricated and not stuck.
Check the brake line for cracks or leaks that could affect brake performance.
Examine suspension components (control arms, bushings, etc.) for damage that could cause misalignment.

5. Reassemble Components

If all components are in good condition, reattach the caliper, ensuring it is properly aligned.
Reinstall the wheel and tighten the lug nuts to the manufacturer's torque specifications (usually around 76 lb-ft for a Camry).
Lower the vehicle back to the ground.
